PIPE-HANGER.

Specification of Letters Patent. Patented J 119 22, 1915.

Application filed December 3, 1914. Serial No. 875,358

To all whom it may concern: 1 I

Be it known that I, HJALMAR G. CAnLsoN, a citizen of the United States, residing at Worcester, in the county of Worcester.- and State of Massachusetts, have invented a new and useful Pipe-Hanger, of which the following is a specification.

This invention relates to a hanger for water, steam and other pipes and the principal objects thereof are to provide a simple construction of hanger that can be made of bar steel to replace the castings and other crude devices that have been used heretofore; and especially to provide a construction which can be formed up in dies in an expeditious and inexpensive manner, and which will be strong and reliable.

Reference is to be had to the accompanying drawings in which Figure 1 is a sectional view showing the first step in the operation of making a preferred form of hanger from a bar of steel, in accordance with this invention; Fig. 2 is a side view of the bar showing its form after the next step of the operation, the original bar being shown in dotted lines; Fig. 3 is a plan of the same; Fig. 4: is a side view showing the next step; and Fig. 5 is a similar view of the complete hanger.

In the formation of the hanger, a straight bar of steel is placed on a cutting die A having a rounded depression a at the edge thereof so that when the cutting member B moves down on it to cut, it will produce a straight blank C having a projecting angular end 0. During this cutting operation the blank is held by a die or plate D.

Although the next set of dies are not shown, the next operation is illustrated in Fig. 2 in which the bar 0 is shown in dotted lines and the shape of it after the operation is performed is shown in full lines. This operation simply bends the bar 0 at two points 0 and forms ribs 0 thereon for strengthening the same. It also bends over the ends at 0 and 0 This blank is then simply bent double at the center so as to form a loop 0 for supporting the pipe. This brings the projecting end 0 over the end 0 and the final step consists in bringing this back into registration and then bending down the end 0 to clamp over the rounded corner of the end 0 as shown in Fig. 5. Thus a hanger is secured having a loop 0 for the pipe, two upright arms 0 and c and a top consisting of the two overlapping ends 0 and 0 This top receives a screwthreaded rod E for supporting it from above. It is to be noted that the bent end 0 is shorter than the end 0 and abuts against the arm 0 to hold the two arms apart while the projection o overlaps the elbow at the base of the end 0 and holds the two arms together. In this way a hanger is secured which is firm and rigid and which constitutes a complete hanger in a single piece. The ribs 0 serve to strengthen it and'give it rigidity. It can be made with any desiredv sized loop 0 for supporting pipes of difi'erent characters.

Although I have illustrated and described only a single embodiment of the invention, I am aware of the fact that many modifications can be made therein by any person skilled in the art without departing from the scopes of the invention as expressed in the claims. Therefore, I do not wish to be limited to all the details of construction herein shown and described, but

What I do claim is 1. As an article of manufacture, a pipe hanger consisting of a piece of bar steel bent double and provided with a passage for a pipe and having an overlapping end ofiset inwardly and engaging the other end to hold the two ends together and a supporting device therefor passing through both of said ends and holding them positively together.

2. As an article of manufacture, a pipe hanger consisting of a piece of metal having its two ends bent inwardly on the same side, one being longer than the other, the longer one having an inward angular projection on the inner end overlapping the other end. said other end engaging the inner side of the opposite side of the pipe hanger to prevent the two ends moving nearer together, and provided with a passage for a plpe.

3. As an article of manufacture, a pipe hanger consisting of a piece of metal having its two ends bent inwardly on the same side, one having an inward angular projection on the inner end overlapping the other, and provided with a passage for a pipe and means for positively holding said ends together.

4. As an article of" manufaet'ure, a pipe hanger, comprising a bottom loop for a pipe,

two substantially parallel arms extending upwardly from the opposite sides of the loop, the ends of 'both of said arms extending inwardly and overlapping, the.

jection on its end fitting. the outer end of the 10 lower end to prevent separation of the arms.

In testimony whereof I have hereunto set my hand, in the presence of two subscribing V witnesses.
